This 20" grit impregnated brush is manufactured specifically for use on the CleanFreak® 'Performer 20' auto scrubber to perform heavy duty scrubbing and stripping. It performs exceptionally well when scrubbing heavy soiled surfaces and grout lines. It may harm tiled surfaces if you are using too aggressive of a solution, or the floor is not properly protected. We also recommend testing this brush in an inconspicuous area, before scrubbing your entire floor, as it is extremely aggressive.
The 1.5 inch bristles will wear down over time. To help extend the life of your brush, we recommend cleaning brush after each use and hanging it up to dry. Excellent for scrubbing of concrete and stripping of quarry tile, terrazzo, and VCT. As always, our brushes will normally equal about 100 pad equivalents.
Unfortunately, I was advised by customer service to buy this product, although, later another CSR advised me this brush would not do the job I bought it for. So, I returned it today. Hopefully, credit will be issued.
